I'll take a stab at it. At trick 3, lead the A ♠ and K ♠. If both opponents follow suit, lead K ♦ then to A♦ ruffing high on a third round. There is roughly a 30% chance an opponent started with a singleton or void in ♦ and 3♠ and can ruff my ♦ leads. Let me know if my math is off here, but it seems to be a 70% chance of success assuming spades broke. If spades didn't break, it seems I will have to run trumps and play for a drop in diamonds. At the table, I might lead the J♦ from dummy before spades only because of the high % of players that will automatically cover with the Q.
